Skip Truck Traders’ new mini compactor

A new mini waste collection vehicle is set to revolutionise urban waste management in Africa, especially in townships. John Edwards, MD of Skip Truck Traders, explains what makes these four-tonne mini compactors fit for purpose.

Our new four-tonne mini compactor is designed specifically for waste collection in townships with narrow access roads where manoeuvrability is limited and also other areas such as housing estates where access for large trucks is either limited or not permitted,” says Edwards.

Designed based on the needs of local metros, Skip Truck Traders’ new mini compactor is a side-loader where 240 ℓ wheelie bins are lifted and tipped into an opening at the top of the vehicle. On either side of the unit is a door that is utilised for hand dumping of plastic bags.

The packer blade inside the unit compacts the waste from the front of the unit to the rear using two hydraulic cylinders setup in a scissor format to maximise space. The pressure setting on the hydraulic system is set at 10 bar to allow for partial compaction only in order to eliminate overloading. The back tailgate lifts up and is hinged in the middle for easy unloading.

“The reason for this design, as well as the compactor’s small size, is to allow the vehicle to reverse to the rear of a regular rear-end loader (REL) compactor, then the packer blade is used to push partially compacted waste into the larger vehicle. The waste is then fully compacted  into the large REL, accommodating between three and four loads before going to the nearest landfill site for dumping,” says Edwards.

A standard REL can take up to three hours to drive to a landfill, dump its contents and drive back. By having three or four mini compactors offloading their contents into a larger vehicle, the smaller waste collection vehicles are able to keep working whilst the large REL is travelling to the dump site – which results in no downtime.

The other advantage of a smaller vehicle is that it can more easily be repurposed after the end of its prime service life. “There is scope for municipalities to donate these vehicles to communities for SMME upliftment after a period of five years,” says Edwards.

Affordable price

A standard REL will typically cost about R2 million. Skip Truck Traders’ new four-tonne mini compactor costs in the region of R650 000 (including truck), meaning that municipalities can purchase three small vehicles at the same cost as a single large truck.

“The vehicle’s smaller size results in other cost savings as well – these include a two-thirds saving on running costs; smaller and more affordable tyres; a reduced fuel bill; and lower maintenance costs,” says Edwards.

The compactor also comes with the same standard guarantee on all of Skip Truck Traders’ vehicles: “If it breaks down within the first 12 months, we will provide a replacement rental vehicle free of charge for the period that it takes for us to do the required repairs.”

Design features

In some places, like the Johannesburg CBD, street sweepers still use plastic bags to collect waste. For this reason, Skip Truck Traders’ mini compactor is designed with side-doors for street cleaners’ waste.

The vehicle could also be used in municipal separation-at-source initiatives, where different waste streams – such as green waste – could be collected and then dropped off at a separate facility not situated at the main landfill.

“One of the design features of the unit is that it does not fully compact the waste, because that would cause it to exceed the vehicles maximum loading capacity. This is calculated based on general waste. Most recyclables are much lighter like plastic bags that can be compacted for optimal loading,” says Edwards.

The mini compactor’s rear is about an inch lower than the rear of a standard REL. To overcome the height difference, a small hydraulic cylinder has been installed to lift the body by about 300 mm, ensuring that the clearances between the two vehicles can be aligned so that waste can be easily transferred from one to the other.

Local manufacturing

The truck’s lifting system is an all-South African design. “The mini compactor is made in South Africa for Africa,” says Edwards.

Skip Truck Traders has also expanded to begin manufacturing its own cylinders. “We recently purchased a range of fully automated CNC lathes, which produce 100% accurate cylinders to our exact specifications,” he concludes.
